(1) Pursuant to Rule 416, there are also being registered such additional shares of Common Stock as may become issuable pursuant to stock splits or similar transactions.

(2) The proposed maximum offering price has been estimated pursuant to Rule 457(h) solely for the purpose of calculating the registration fee. It is not known how many of these shares will be purchased or at what price. A portion of the shares (83,500 shares) are issuable upon exercise of options with fixed exercise prices ranging from $.90 to $.96. Pursuant to Rule
457(h)(1), the aggregate offering price and the fee have been computed upon the basis of the price at which the options may be exercised. The shares representing unissued options (266,500 shares) do not have a fixed exercise price. The proposed maximum offering price per share for such shares has been calculated pursuant to Rule 457(h) as $.99, which is the average of the high and low prices of the Registrant's Common Stock as listed on Nasdaq on December 20, 2001.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Section 67 of Chapter 156B of the Massachusetts General Laws provides that indemnification of directors, officers, employees, and agents of the Registrant may be provided to the extent specified in or authorized by (i) its articles of organization, (ii) a by-law provision adopted by the stockholders, or (iii) a vote adopted by the holders of a majority of the shares of stock entitled to vote on the election of directors.

Section 6 of the Registrant's Articles of Organization, as amended, provides that no director of the Registrant shall be personally liable to the Registrant or its stockholders for monetary damages by breach of fiduciary duty as a director to the extent provided by applicable law notwithstanding any provision of law imposing such liability; provided, however, that Section 6 shall not eliminate the liability of a director (i) for any breach of the director's duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under section 61 or 62 of the Business Corporation Law of the Commonwealth of Massachusetts, or (iv) for any transaction from which the director derived an improper personal benefit.

4

omission occurring prior to the date on which Section 6 became effective. No amendment to or repeal of Section 6 shall apply to or have any effect on the liability or alleged liability of any director of the Registrant for or with respect to any acts or omissions of such director occurring prior to such amendment or repeal.

ITEM 9. UNDERTAKINGS.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post- effective amendment to this registration statement:

(i) To include any additional or changed material information on the plan of distribution.

(2) For the purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(5) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. in the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the act and will be governed by the final adjudication of such issue.

Exhibit 4

TECHNICAL COMMUNICATIONS CORPORATION
2001 STOCK OPTION PLAN

1. Purpose of the Plan. The purposes of this 2001 Stock Option Plan are to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to the Employees, Directors and Consultants of the Company and to promote the success of the Company's business.

Options granted hereunder may be either Incentive Stock Options or Non-statutory Stock Options, at the discretion of the Board and as reflected in the terms of the written option agreement.

2. Definitions. As used herein, the following definitions shall apply:

a) "Board" shall mean the Committee, if one has been appointed, or the Board of Directors of the Company, if no Committee has been appointed.

b) "Code" shall mean the Internal Revenue Code of 1986, as amended.

c) "Common Stock" shall mean the Common Stock, $.10 par value, of the Company.

d) "Company" shall mean Technical Communications Corporation, a Massachusetts corporation.

e) "Committee" shall mean the Committee appointed by the Board of Directors in accordance with paragraph (a) of Section 4 of the Plan, if one is appointed.

f) "Consultant" shall mean any person who is engaged by the Company or any Subsidiary to render consulting services and is compensated for such consulting services.

g) "Continuous Status as an Employee, Consultant or Director" shall mean the absence of any interruption or termination of service as an Employee, Consultant or Director. Continuous Status as an Employee, Consultant or Director shall not be considered interrupted in the case of sick leave, military leave, or any other leave of absence approved by the Board; provided that such leave is for a period of not more than ninety (90) days or reemployment upon the expiration of such leave is guaranteed by contract or statute.

h) "Director" shall mean any director of the Company.

i) "Employee" shall mean any person, including officers and directors, employed by the Company or any Parent or Subsidiary of the Company. The payment of a director's fee by the Company shall not be sufficient to constitute "employment" by the Company.

j) "Incentive Stock Option" shall mean an Option intended to qualify as an incentive stock option within the meaning of Section 422 of the Code.

k) "Non-statutory Stock Option" shall mean an Option not intended to qualify as an Incentive Stock Option.

l) "Option" shall mean a stock option granted pursuant to the Plan.

p) "Parent" shall mean a "parent corporation", whether now or hereafter existing, as defined in Section 424(e) of the Code.

q) "Plan" shall mean this 2001 Stock Option Plan.

r) "Share" shall mean a share of the Common Stock, as adjusted in accordance with Section 11 of the Plan.

s) "Subsidiary" shall mean a "subsidiary corporation", whether now or hereafter existing, as defined in Section 424(f) of the Code.

3. Stock Subject to the Plan. Subject to the provisions of Section 12 of the Plan, the maximum aggregate number of shares of Common Stock for which Options may be granted under the Plan is 350,000 shares of Common Stock. The Shares may be authorized, but unissued or reacquired Common Stock.

If an Option should expire or become unexercisable for any reason without having been exercised in full, the unpurchased Shares that were subject thereto shall, unless the Plan shall have been terminated, become available for future grant under the Plan.

Notwithstanding any other provision of the Plan, shares issued under the Plan and later repurchased by the Company shall not become available for future grant or sale under the Plan.

4. Administration of the Plan.

(a) Procedure. This Plan shall be administered by the Board of Directors of the Corporation. The Board may, from time to time, delegate any of its functions under this plan to one or more Committees. All references in this Plan to the Board shall also include the Committee or Committees, if one or more have been appointed by the Board. From time to time, the Board may increase the size of the Committee or committees and appoint additional members thereto, remove members (with or without cause) and appoint new members in substitution therefor, fill vacancies however caused, or remove all members of the Committee or committees and thereafter directly administer the Plan. No member of the Board or a committee shall be liable for any action or determination made in good faith with respect to the Plan or any options granted under it. If a Committee is appointed by the Board, a majority of the members of the Committee shall constitute a quorum, and all determinations of the Committee under the Plan may be made without notice or meeting of the Committee by a writing signed by a majority of Committee members. The Board may delegate the power to select Directors and officers to receive Options under the Plan, and the timing, pricing and amount of such Options to a Committee, all members of which shall be "non-employee directors" within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

b) Powers of the Board. Subject to the provisions of the Plan, the Board shall have the authority, in its discretion: (i) to grant Incentive Stock Options or Non-statutory Stock Options; (ii) to determine, upon review of relevant information and in accordance with Section 8(b) of the Plan, the fair market value of the Common Stock; (iii) to determine the exercise price per share of Options to be granted, which exercise price shall be determined in accordance with Section 8(a) of the Plan; (iv) to determine the Employees, Consultants or Directors to whom, and the time or times at which, Options shall be granted and the number of shares to be

2

represented by each Option; (v) to interpret the Plan; (vi) to prescribe, amend and rescind rules and regulations relating to the Plan; (vii) to determine the terms and provisions of each Option granted (which need not be identical) and, with the consent of the holder thereof, modify or amend each Option; (viii) to accelerate or defer (with the consent of the Optionee) the exercise date of any Option, consistent with the provisions of Section 5 of the Plan; (ix) to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of an Option previously granted by the Board; and (x) to make all other determinations deemed necessary or advisable for the administration of the Plan.

c) Effect of Board's Decision. All decisions, determinations and interpretations of the Board shall be final and binding on all Optionees and any other holders of any Options granted under the Plan.

5. Eligibility

a) Non-Statutory Stock Options may be granted only to Employees, Consultants, or Directors. Incentive Stock Options may be granted only to Employees. An Employee, Consultant or Director, who has been granted an Option may, if he is otherwise eligible, be granted an additional Option or Options.

b) Neither the Plan nor any Option granted hereunder shall confer upon any Optionee any right with respect to continuation of employment, consulting relationship or directorship with the Company, nor shall it interfere in any way with his or her right or the Company's right to terminate his or her employment, consulting relationship or directorship at any time.

6. Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board of Directors or its approval by the shareholders of the Company as described in Section 18 of the Plan. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 14 of the Plan.

7. Term of Option. The term of each Incentive Stock Option shall be ten (10) years from the date of grant thereof or such shorter terms as may be provided in the Option Agreement. The term of each Option that is not an Incentive Stock Option shall be determined by the Board and set forth in the Option Agreement. However, in the case of an Incentive Stock Option granted to an Optionee who, at the time the Incentive Stock Option is granted, owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option shall be five (5) years from the date of grant thereof or such shorter time as may be provided in the Option Agreement.

8. Exercise Price and Consideration.

(a) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Board, but shall be subject to the following: In the case of an Incentive Stock Option granted to an Employee who, at the time of the grant of such Incentive Stock Option, owns stock possessing more than ten (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the fair market value per Share on the date of grant.

In the case of an Incentive Stock Option granted to any other Employee, the per Share exercise price shall be no less than 100% of the fair market value per Share on the date of grant.

(b) Fair Market Value. The fair market value per Share shall be the mean of the bid and asked prices (or the closing price per share if the Common Stock is listed on the National Association of Securities Dealers Automated Quotation ("NASDAQ") National Market System) of the Common Stock for the date of grant, as reported in The Wall Street Journal (or, if not so reported, as otherwise reported by the NASDAQ System) or, in event the Common Stock is listed on a stock exchange, the fair market value per Share shall be the closing price on such exchange on the date of grant of the Option, as reported in The Wall Street Journal.

3

(c) Form of Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Board and may consist entirely of cash, check, other Shares of Common Stock having a fair market value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, or any combination of such methods of payment, or such other consideration and method of payment for the issuance of Shares to the extent permitted under Chapter 156B of the Massachusetts Corporation Law. In making its determination as to the type of consideration to accept, the Board shall consider if acceptance of such consideration may be reasonably expected to benefit the Company.

9. Procedure for Exercise of Option; Rights as a Shareholder. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Board, including performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the Plan; provided, however,

An Option may not be exercised for a fraction of a Share.

An Option shall be deemed to be exercised when written notice of such exercise in the form required by the Option Agreement has been given to the Company in accordance with the terms of the Option Agreement by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may, as authorized by the Board, consist of any consideration and method of payment allowable under Section 8(c) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidence such Shares, no right to vote or receive dividends or any other right as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such stock certificate promptly upon exercise of the Option. Upon receipt by the Company of written notice of exercise of the Option in the form required by the Option Agreement and full payment for the Shares with respect to which the Option is exercised, the Optionee shall be deemed to be the holder of record of the Shares, notwithstanding that certificates representing such Shares shall not then be actually issued and delivered to the Optionee. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 12 of the Plan.

Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for purchase under the Option, by the number of Shares as to which the Option is exercised.

10. Certain Events Affecting Exercisability of Incentive Stock Options.

a) Termination of Status as an Employee, Consultant or Director. With respect to Incentive Stock Options, in the event of termination of an Optionee's Continuous Status as an Employee, Consultant or Director
(as the case may be), such Optionee may, but only within thirty (30)
days (or such other period of time not exceeding three (3) months as is determined by the Board, with such determination being made at the time of grant of the Option) after such event of termination of an Optionee's Continuous Status as an Employee, Consultant or Director (as the case may be) (but in no event later than the date of expiration of the term of such Incentive Stock Option as set forth in the Option Agreement), exercise their Incentive Stock Option to the extent that the Optionee was entitled to exercise it at the date of such termination. To the extent that the Optionee was not entitled to exercise the Incentive Stock Option at the date of such termination, or if the Optionee does not exercise such Incentive Stock Option (which the Optionee was entitled to exercise) within the time specified herein, the Incentive Stock Option shall terminate.

4

b) Disability of Optionee. With respect to Incentive Stock Options, notwithstanding the provisions of Section 10(a) above, in the event of termination of an Optionee's Continuous Status as an Employee, Consultant or Director (as the case may be) as a result of such Optionee's total and permanent disability (as defined in Section 22(e)(3) of the Code), the Optionee may, but only within six (6) months (or such other period of time not exceeding twelve (12) months as is determined by the Board, with such determination being made at the time of grant of the Incentive Stock Option) from the date of termination (but in no event later than the date of expiration of the term of such Incentive Stock Option as set forth in the Option Agreement), exercise the Incentive Stock Option to the extent the Optionee was entitled to exercise it at the date of such termination. To the extent that the Optionee was not entitled to exercise the Incentive Stock Option at the date of termination, or if the Optionee does not exercise such Incentive Stock Option (which the Optionee was entitled to exercise) within the time of specified herein, the Incentive Stock Option shall terminate.

c) Death of Optionee. With respect to Incentive Stock Options, notwithstanding the provisions of Section 10(a) above, in the event of the death of an Optionee:

i. who is at the time of their death an Employee, Consultant or Director of the Company and who shall have been in Continuous Status as an Employee, Consultant or Director since the date of grant of the Incentive Stock Option, the Incentive Stock Option may be exercised, at any time within six (6) months following the date of death (but in no event later than the date of expiration of the term of such Incentive Stock Option as set forth in the Option Agreement), by the Optionee's estate or by a person who acquired the right to exercise the Incentive Stock Option by bequest or inheritance, or beneficiary designation, but only to the extent of the right to exercise that would have accrued had the Optionee continued living and remained in Continuous Status as an Employee, Consultant or Director six (6) months after the date of death; or

ii. which occurs within thirty (30) days (or such other period of time not exceeding three (3) months as is determined by the Board, with such determination being made at the time of grant of the Incentive Stock Option) after the termination of Continuous Status as an Employee, Consultant or Director, the Incentive Stock Option may be exercised, at any time within Six (6) months following the date of death (but in no event later than the date of expiration of the term of such Incentive Stock Option as set forth in the Option Agreement), by the Optionee's estate or by a person who acquired the right to exercise the Incentive Stock Option by bequest or inheritance, or beneficiary designation, but only to the extent of the right to exercise that had accrued at the date of termination.

11. Non-Transferability of Options. An Option may not be sold, pledged, assigned hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent and distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee.

12. Adjustments Upon Changes in Capitalization or Merger. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per share of Common Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected" without receipt of consideration. Such adjustments shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares

5

of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option.

In the event of the proposed dissolution or liquidation of the Company, each outstanding Option will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Board. The Board may, in the exercise of its sole discretion in such instances, declare that any Option shall terminate as of a date fixed by the Board and give each Optionee the right to exercise his Option as to all or any part of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation where the Company is not the surviving corporation, the Option shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation. In the event that such successor corporation refuses to assume the Option or to substitute an equivalent option, the Board shall, in lieu of such assumption or substitution, provide for the Optionee to have the right to exercise the Option as to all of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. If the Board makes an Option fully exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Board shall notify the Optionee that the Option shall be fully exercisable for a period of thirty (30) days from the date of such notice, and the Option will terminate upon the expiration of such period.

13. Time of Granting Options. The date of grant of an Option shall, for all purposes, be the date on which the Board makes the determination granting such Option. Notice of the determination shall be given to each Employee, Consultant or Director to whom an Option is so granted within a reasonable time after the date of such grant.

14. Amendment and Termination of the Plan.

a) Amendment and Termination. The Board may amend or terminate the Plan from time to time in such respects as the Board may deem advisable; provided that the following revisions or amendments shall require approval of the shareholders of the Company in the manner described in Section 18 of the Plan:

i. any increase in the number of Shares subject to the Plan, other than in connection with an adjustment under Section 12 of the Plan;

ii. any change in the designation of the class of person eligible to be granted Options; or

iii. any material increases in the benefit accruing to participants under the Plan.

b) Shareholder Approval. If any amendment requiring shareholder approval under Section 14(a) of the Plan is made, such shareholder approval shall be solicited as described in Section 18 of the Plan.

c) Effects of Amendment or Termination. Any such amendment or termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated, unless mutually agreed otherwise between the Optionee and the Board, which agreement must be in writing and signed by the Optionee and the Company.

15. Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, the so-called state "blue sky" or securities laws, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

6

As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investments and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law.

16. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

17. Option Agreement. Options shall be evidenced by written option agreements (each an "Option Agreement") in such form as the Board shall approve. The Option Agreement for each Nonstatutory Stock Option granted hereunder shall provide that such Option will not be treated as an Incentive Stock Option.

18. Shareholder Approval.

(a) Continuance of the Plan shall subject to approval by the shareholders of the Company within twelve (12) months before or after the date the Plan is adopted. If such shareholder approval is obtained at a duly held shareholders' meeting, it must be obtained by the affirmative note of the holders of a majority of the outstanding shares of the Company and shall be solicited substantially in accordance with Section 14(a) of the Exchange Act and the rules and regulations promulgated thereunder.

(b) If any required approval by the shareholders of the Plan itself or of any amendment thereto is solicited at any time otherwise than in the manner described in Section 18(a) hereof, then the Company shall, at or prior to the first annual meeting of shareholders held subsequent to the granting of an Option hereunder to an officer or director, do the following:

i. furnish in writing to the holders entitled to vote for the Plan substantially the same information which would be required (if proxies to be voted with respect to approval or disapproval of the Plan or amendment were then being solicited) by the rules and regulations in effect under Section 14(a) of the Exchange Act at the time such information is furnished; and

ii. file with, or mail for filing to, the Securities and Exchange Commission four copies of the written information referred to in subsection (i) hereof not later than the date on which such information is first sent or given to shareholders.

Re: Registration Statement on Form S-8

Ladies and Gentlemen,

We have acted as counsel for Technical Communications Corporation, a Massachusetts corporation (the "Company"), in connection with the preparation of the Company's Registration Statement on Form S-8 proposed to be filed with the Securities and Exchange Commission on or about December 28, 2001 (the "Registration Statement").

The Registration Statement covers the registration of shares of common stock, $0.10 par value per share, of the Company (the "Shares"), which are issuable by the Company pursuant to its 2001 Stock Option Plan (the "Plan").

We have reviewed the corporate proceedings of the Company with respect to the authorization of the Plan by the Board of Directors, and the issuance of the Shares thereunder. We have also examined and relied upon originals or copies of such corporate records, instruments, agreements, or other documents of the Company, and certificates of officers of the Company as to certain factual matters, as we have deemed necessary or appropriate as a basis for the opinions hereinafter expressed. In our examination, we have assumed the genuineness of all signatures, the conformity to the originals of all documents reviewed by us in original or copy form, and the competence of each individual executing any document.

This opinion is limited solely to the Massachusetts Corporation Laws, as applied by courts located in Massachusetts.

This opinion may be relied upon only by you in connection with the above transactions, and it may not be used or relied upon by any other person for any purpose whatsoever, other than as specifically required by law, without, in each instance, our prior written consent. We hereby consent to the filing of this opinion, as an exhibit to the Registration Statement.

Very truly yours,
